Beverly Hills and Santa Monica hotel recommendations

Anyone have good hotel recommendations for Beverly Hills and Santa Monica?

This is part of our Honeymoon trip so budget is reasonable, but want to get the most out of our money at the same time! I like high-end, luxury generally and more so as its a special trip, whereas DP couldn't really care less so we will probably both do a bit of compromising in that respect!

So far we have a lose itinerary, we are planning on flying to Vegas, then internal flights to San Francisco. Then driving from SF to LA - we are having one night stop over in San Luis Obispo on the way. Then Beverly Hills for a few nights before finishing off in SM.

Oh Costa Shutters sounds like a winner then! I know it's in a great location as well.

We are looking at The Beverly Hills Hotel for La but I don't want to spend the extra money unless it's definitely worth it as I have a feeling I will need as much spending money as I can get my hands on!
